Trial Information

Foscarnet Treatment of Serious CMV Retinitis Infection in Patients With Acquired Immunodeficiency Syndrome

Foscarnet is active in vitro (test tube) against herpes viruses, including CMV, by
inhibiting the virus DNA polymerases, enzymes necessary for virus replication, without
affecting cellular DNA polymerases. Opportunistic CMV disease in AIDS is usually seen as
retinitis, colitis, esophagitis, hepatitis, pancreatitis, encephalitis, or pneumonia.
Ganciclovir has been used to treat AIDS patients with CMV disease but can cause severe
neutropenia (very low neutrophil cell counts). Foscarnet does not suppress the production of
neutrophils or other leukocytes (myelosuppression) and has shown in vitro activity against

Treatment is given for a total of 10 weeks with a 2-week induction regimen followed by
randomization to daily maintenance foscarnet for 8 weeks. If induction therapy is tolerated
without unexpected toxicity, patients are allowed to self-administer foscarnet at home via
central venous catheter and may receive up to 11 days of induction therapy by
self-administration on an outpatient basis. Foscarnet will be administered in open-label
fashion so that both investigator and patient will know the dose. Within the study, there
are 8 patients who upon entering the 2nd week of maintenance foscarnet therapy are treated
with zidovudine (AZT).
